The VPN is what currently allows me to play at all with my current internet connection so can't really turn off the VPN. How come ENT doesn't allow one to play with VPN?

Your Warcraft III username: Slino
Realm/Gateway: Northrend (Europe)
Why are you banned: rangeban
Why you should be unbanned: Switched from playing on phone net to home net with VPN. Guess it didn't like that I suddenly appeared to be at another location than the last time I played.
